⭐ ESSENTIAL: Get field definitions, types, display names, and validation rules for a Kintone app. ⚠️ Use
AI agents call kintone_get_form_fields to retrieve information from Mcp Kintone Lite without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves schema/metadata information about Kintone app fields. It performs a read-only query operation that returns field definitions and configuration. There are no side effects, no data modification, no execution of arbitrary code, and no destructive operations. The blast radius of misuse is minimal—an attacker gains knowledge of the app structure but cannot manipulate or access actual records.
From the tool's definition Tool name contains 'get' and description states 'Get field definitions, types, display names, and validation rules' - retrieves metadata about form structure without modifying or deleting data.

⭐ ESSENTIAL: Get field definitions, types, display names, and validation rules for a Kintone app. ⚠️ Use. It is categorised as a Read tool in the Mcp Kintone Lite MCP Server, which means it retrieves data without modifying state.
Register the Mcp Kintone Lite MCP server in PolicyLayer and add a rule for kintone_get_form_fields: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Kintone Lite. Nothing to install.
kintone_get_form_fields is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the kintone_get_form_fields rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
